FIFYOLDING BEDSTEAD.

SPECIFICATION forming part of Letters Patent No. 364,285, dated June '7, 1887.

Serial No. 223,229. (No model.)

To all whom it may concern:

Be it known that I, CHARLES W. PEOBLE, of Troy, in the county of Rensselaer and State of New York, have invented. new and useful Improvements in Folding Bedsteads, of which the following is a specification.

My invention relates to improvements in that class of folding bedsteads for which Letters Patent No. 352,568 of the United States were granted to me on the 16th day of November, 1886;,and the object of my present improvement'is to provide a simple and efficient shifting fulcrum which cannot be misplaced in putting it together. This object I attain by means of the mechanism illustrated in the accompanying drawings,which is herein referred to, and forms part of this specification, and in which Figure 1 is a vertical section of the standing frame, with the movable bed-frame shown in side elevation in its horizontal position; Fig. 2, a like view with the movable bed in its vertical position; Fig. 3, an enlarged side elevation of the track-piece and segment of my shifting fulcrum for folding beds; Fig. 4, an edge view of same, and Fig. 5 a perspective view of the segment for said shifting fulcruin.

In folding bedsteads having shifting fulcrums formed of toothed racks and quadrants a frequent difficulty is met in properly fixing the movable bed-frame into its place in the standing frame, owing to a liability of entering the teeth or cogs of the quadrant into the wrong spaces between the teeth on the rack, thereby requiring the movable frame to be frequently lifted in and out of place until the parts were properly put in gear. By myimprovemen't this difficulty is entirely avoided, and a quiet, smooth, and easy-moving fulcrum is substituted for one that is frequently rough and noisy in its movements.

As represented in the drawings, A is the standing frame and B the movable bed-frame of a folding bedstead, both of which may be made in any of the most desirable forms suitable for such purpose. Each of the side pieces, a, of the standing frame has a trackpiece, 0, secured to its inner side, as represented in dotted lines in Figs. 1 and 2, and

they should be fixed exactly opposite each other, so that their positions will be in abs0- lute correspondence. Said track-pieces consist of a smooth straight horizontal rib or track, 0, having on its upper side an angular point or plate, 0', whose edges should have the form of cyeloidal curves, which intersect each other at the apexof the point e. The movable bed-frame B has on the outer side of each of its side pieces, I), a quadrant, D, whose convex edge is smooth, and which has at each end of the curve a round stud, d, projecting from one side of said quadrant. The distance between said studs should be such that when one of them is resting on the track 0 the other will be near the apex of the point 0, as shown in Fig. 3. Then as the quadrant D is rocked on the track a the said studs follow the curved edges toward the point 0, against which edges said studs will bear throughout the movement of the quadrant, and thereby any Y slipping movement of the parts will be prevented.

It will readily be seen that in putting the movable bed-frame B into its place in the standing frame A, if the two studs (Z are placed at the opposite sides of the angular point a, the two parts will be certain to adjust them selves in place.

I claim as my invention 1. In a folding bed, the combination, with a standing frame, A, whose side pieces are each provided with a track-piece, O, that consists of a straight smooth-face track, 0, fixed crosswise of said side pieces, and having an angular point, e, erected at the side of said track, so as to leave the latter unobstructed, of a movable bed-frame, B, fitted to oscillate in the standing frame A, and having at each side a plain-edge quadrant, D, whose convex edge is fitted to roll on the track a, 'so that its center of motion will move ina straight line, the, said quadrant being provided with projecting studs (1, which engagewith opposite edges of the angular point 0, as and for the I purpose specified.

2. A rolling fulcrum for folding beds, consisting of a trackpiece, G, composed of a straight smooth-face track, 0, which has an angular point, a, erected at its side, so as to ICO I leave the latter unobstructed, and a smooth- I the angular point a, as and for the purpose faced quadrant, D, whose convex edge is fitted to roll on the track 0, so that its center of motion will move in a straight line that is par allel t0 the upper face of said track, the said Witnesses:

quadrant being provided with side projecting l \VM. H. LOW,
